Factors to Consider When Selecting Hydraulic Piston Oil Seals

What Are Hub Oil Seals?

The designation 31x43x10 provides critical dimensions of the oil seal. Here, 31 indicates the inner diameter (ID) in millimeters, 43 represents the outer diameter (OD), and 10 denotes the width of the seal in millimeters. The oil seal also has a percentage component, possibly alluding to its material composition or operational pressure resistance, although further context is required for precise interpretation.

Hub oil seals are specifically designed to prevent the escape of oil from the wheel hub of vehicles. They are typically made from durable materials such as rubber, polyurethane, or composite materials, engineered to withstand the harsh conditions of the automotive environment. These seals fit snugly around the axle or hub, creating a barrier that retains lubricants while keeping dirt, debris, and moisture from entering.

2. Contaminant Exclusion These seals protect sensitive mechanical components from dirt, dust, and water, which can cause corrosion or damage to the internal components. This capability is particularly important in harsh working environments.
